Thanks. This may seem like a trivial question to regular users but in the past I've been able to upload way bigger photos but on this occasion I was severely constrained by size limitation (hence the narrow tall images). Any idea why this might be so?

It's probably a matter of JPEG compression quality.

There are two different limits on uploads: 1) no more than 1024 pixels on either side, and 2) file length no more than 300 KB.

Images that exceed the 1024-pixels limit are automatically downsized.

However, images that fit the 1024-pixels limit but exceed 300 KB are not automatically downsized; they are simply rejected. It then falls to the user to re-save the image as a lower quality JPEG so as to produce a smaller file.

If you're using Photoshop, it can also help to "Save for Web & Devices" rather than a simple "Save As". Save for Web & Devices somehow manages to produce a slightly smaller file at the same quality.

Thanks for the kind remarks Stefano B and Sumguy01.

rjlittlefield, that puts things in perspective, cheers. I noticed the dimension-wise larger photos were all <300kb and I guess I never really gave thought about how pictures of equal amount of pixels can yield different digital volume.
