The image resize script...
    #8512673 -

Ythan,

I know you or one of the other tech admins probably worked hard to implement this resize script... But it sucks balls. Totally sucks balls. It resizes the images and compresses them to hell which makes them look like cheap shitty porn images circa the 1990s.

Can you at least PLEASE remove this script, at least for supporters? I hate photoshopping the bejesus out of an image so it looks perfect then uploading it here and seeing it look like compressed bullshit. :frown: :frown: :frown:

I'm not really sure what you're talking about, could you please show me a comparison between the original image, the way the Shroomery resizes it, and the way you think it should be resized? Also, if you're photoshopping the bejesus out of an image why not just save it with the proper dimensions in the first place?

Because higher res allows you to see more detail than low res. Here is the latest example:

http://www.impakt.net/~tyler/new/weilii/buds/bk1.jpg

Perhaps I have another... hold up
Damnit I have so many pictures uploaded I can't find my other example.

Point is: the resize script kills detail and tends to add darkness. How about for supporters images under 1280 (H or W) don't get resized? I always try to keep my "web ready" images under those dimensions. Would that be agreeable?

    #8513208 -

Aaah okay, I totally forgot about that feature. It only kicks in if the file size of an image you're uploading is larger than the maximum allowed (for supporters it's 512KB). In those cases it does try increasingly aggressive optimizations to bring down the file size. It's actually meant as a user-friendly alternative to simply rejecting the upload after a long transfer. To prevent images you upload from being modified you should make sure they're beneath the maximum file size. If your image is a JPEG you can often increase the compression without much noticeable difference. For example, one half of the image below is from the original which was 588KB. The other half I recompressed to a scant 150KB. Can you tell which is which?



And if I had the lossless source image, the 150KB side would look even better.

Anyway I apologize for the confusion and inconvenience, and I'll try tweaking the script to squeeze some additional quality out of the processed images. But your best bet is probably to handle any compression yourself to ensure the image is small enough that it doesn't require modification on our end.

The main problem with the compression script is that it generates an image that is only 600 pixels wide.  If it made an image that was 1024 or 1280 wide it would be a lot better.

For those that browse on small screens, large pictures in threads are highly annoying.  (Well, they used to be... the new code that puts in scroll bars fixes that issue.)

No, not a mistake! The poster did what we are supposed to do and used a decent jpg compression. That image is only 225kb, which is allowed.

yeah, i have noticed this and i'm not too fond of it. i would just rather see a thumbnail or something. but most of the time, when i wanna see a picture in full size i either click on it (if it's a thumbnail) or right click + view pic.

is there a way to not have those scrollbars?

Ahhh, alright. I try to avoid compressing my images at all because I'm a big fan of quality pictures. But jpeg compression of 8 or 9 in Photoshop only sacrifices a tiny bit of quality and a reduces file size immensely. I'll start doing that. Gracias mang.

I think a lot of people are going to stop posting pictures because many people do not have the software required to resize images. If you try to upload one now thats too big you get an error and the image isnt resized.

To get around this (which is a pain in the ass) I had to pick an image I DIDNT want uploaded followed by the ones I did. Now the error only happes for the first picture thats too big and the rest get resized as normal.

Maybe you should have it so that if your image is the right size... great, but if not it will resize it for you. I admit you lose SOME quality, but do 90% or shroomery members have some sort of photo editor?

Re: The image resize script... [Re: legallyhomeless]

That should not be the case... I did make some changes to the upload script, but only to attempt more fine-grained levels of optimization when an image exceeds the maximum size. To test, I used a regular non-admin, non-supporter account with an upload limit of 256KB and uploaded the infamous test photo http://www.impakt.net/~tyler/new/weilii/buds/bk1.jpg which is 588KB. The upload succeeded and produced the optimized image http://www.shroomery.org/forums/files/08-24/338590041-bk1.jpg which is 212KB. The only time an upload should be refused is if it's compressed to 30% quality and resized to 600px at its largest dimension and it still exceeds the maximum filesize. However, this is similar to how it always was. Can you please give me a link to the picture which you're unable to upload by itself?

All of the pictures are stored on my computer. Only after you said you made thoes changes did I expirence any problems. Its not that big of an issue having to pick a picture I dont want uploaded first...not that I know I can still upload.

The one that failed was the one that I picked to be in the first upload box.



Now when I tried to upload the picture above, I used a very very small image and then that one. BOTH uploaded!

i know all about right click + view image, if you read my previous posts you'll see that i already use do that with most images i want to see in detail.

when there is huge image in a thread, i'd like to be able to see the entire picture before i decide if i want more detail or not. sometimes, i don't even know what i'm looking at till i start moving the scrollbar.

Okay well I took some time and evaluated a couple options. I almost went with the jQuery autoscale plugin since it's pretty slick and I want to switch to jQuery anyway. However, I don't think it's exactly what we need... there's no way to view an image full-sized on a small monitor, and there could be performance problems in long threads with lots of images. In the end I went with a simple option at the bottom of the display preferences:



The default is 0 or disabled, set it to 800 for the old behavior. Hope this helps and let me know if you encounter any problems. :smile:

Okay I made one final change to the upload script. I tried to strike a better balance between aggressive compression settings and decreasing the image dimensions. Instead of compressing the fuck out of the image and then resizing it if necessary, it alternates between the two, gradually reducing both the quality and dimensions. This goes against the original request in this thread ("don't resize images if at all possible"), but I swear to god, if one more person with a .25MB upload limit complains that their 12MB image isn't reproduced in perfect quality, I'm replacing our gallery with a link to Imageshack. Compress it yourself if you don't like the automated results!

I've used it on some other projects but not on the Shroomery yet. I really should have started using a framework for this site already but a lot of the scripts were written before there were good options available. It'll be a lot of work to update all our scripts to use a framework, but that's probably what I'll do eventually to ease maintenance. I'm trying to decide between jQuery and MooTools, I like MooTools but I'll probably go with jQuery because of the larger community.

If you have windows, you can:
1. right-click the picture - select "open with"
2. select "paint"

With paint now displaying the pic:
3. click on the "image" button at the top
4. select "attributes..."

A window pops up and tells you picture size on disc, resolution and width & height in pixels, cm, or inches. You can now:
5. Change the values for width & weight

You should try to keep the two variable numbers in proportion to each other when resizing, to keep the pic from stretching too much.  For example if your width & height values are 2000 & 1500 respectively. You could reduce the pic size by a quarter by changing them to 1500 & 1125 respectively.
Hope this helps, I'm pretty sure paint is standard in windows.
