Some tips on reducing file size:
Cameras (usually) save in the highest quality format they can, with huge
resolutions. This is why "fresh" pictures are about 10+ MB nowadays. There are free utilities that will resize images, the most popular being GIMP
(And the Mac Version
). Adobe Photoshop will also do the trick, if you happen to have that. I typically save my images in some fixed proportion of the original, always less
than 1000 pixels x 1000 pixels.
Cameras usually save in .jpg or .bmp, both of which are pretty bloated filetypes. MS Paint (And GIMP) will "save as" in the .png format, an excellent format that greatly
reduces file size without any noticeable loss in quality.
If you're concerned, these changes won't make the picture any smaller than what the forum displays in a post nor do they noticeably decrease quality. I typically can change a picture from my Samsung 12 megapixel camera from being about 15 MB to about 250 KB with no picture difference. By doing that, I could have 60 pictures instead of just one!
I also recommend hosting your image off site (Photobucket
are both good and free, Imgur is definitely my favorite though!) Then, use the forum's Img tags ([img]photo_url[/img]) to display them here like you would. Then there's no strain whatsoever on the server's HDD.
