mBb ----- most likely no issue. Just agreeing with Roberta here.
OrchidBoard allows uploaded pics to be approx 1024 x 768 (width by height pixels) for landscape type images, or 768 x 1024 (for portrait type images).
If uploading loading images - can scale them to roughly those sizes, which can give a better view of the regions of interest when compared with small images of full plants.
Even close-up shots are useful.
If a relatively small photo is uploaded, or if the regions of interest can't be seen very well (due to lack of resolution or lack of detail), then that can make it harder to get an idea of what is going on with the pseudobulbs.
