De rien. But yeah, @Emdek is doing some truly great work.
Server space comes at a premium, hence the small attachment limit. I'd recommend an external service when you want to attach bigger images, but for PNG and JPEG I should probably write a little guide.
Long story short, for screenshots PNG is typically the right choice. If you want to use lossless PNG, use
optipng -o7. If you don't care about losing some color accuracy, use
pngquant. For JPEG use
jpegtran -copy none -progressive -optimize file.jpg > file-opt.jpg. Applying this principle to your screenshot (which probably should've been in PNG :) ):
$ du -h trop\ ptit.jpg
32K trop ptit.jpg
$ jpegtran -copy none -progressive -optimize trop\ ptit.jpg > trop\ ptit-opt.jpg
$ du -h trop\ ptit-opt.jpg
28K trop ptit-opt.jpg
Okay, it's not a giant improvement in this case, but it's still a lossless 4 kiB improvement. ;)
The bigger question is how to easily do all this in Windows. :devil: C'est la vie and so it goes.
Edit: but since we have a bit more space here than on the last server, I upped it to 50 kiB. Almost double of 30. :cheers:
