Artist, long time reader, first time poster

3. I've been using imgbb.com for my sporadic image posts.

Since you might have a real portfolio, it seems that a good site that allows you to manage galleries.

I am not endorsing, but just passing along what my cousin, a professional artist, told me.

I want to encourage you to create a website of your photographs. You can limit the size of the mages you post so they will be difficult to steal. An image of 72 dpi and 1000 pixels on the wider side is not large enough to reproduce but plenty large for good visibility on line. I use Icompendium.com. It's an easy system to navigate, and the owner, Van Strokes, is available to help you get started if you don’t want to waste time trying to figure out its intricacies.

FWIW, contest images are limited to a bit under 1 megabyte in size here, though some folks with really high quality pix have posted 1.5 megabytes and even 2.5 megabytes in threads. If this is confusing, just ask in the photography group. Lots of friendly and helpful people there.
