What would I use when setting up a gallery for many members to submit to?
I am thinking, Members’ Gallery, as it is a gallery belonging to all the members, but I frequently see the use of just Members Gallery.

A "members' gallery" is a gallery belonging to the members. A "members gallery" is a gallery of the members.
If all the pictures in your gallery are of your members, then you've got yourself a "members gallery". If the gallery contains pictures by or for your members, then you're offering your members a gallery: it's your members' gallery.
For reference, here's a picture of Madam Tussaud's Presidents Gallery (note: no apostrophe). It contains lifelike wax figures of all 44 US presidents; but I doubt a single US president has ever visited it:
Members' Gallery is preferable, in that it conveys the meaning of the phrase more exactly: it correctly identifies the members, plural, as possessing the gallery, in the linguistic sense. However, if the non-possessive members is thought of as a simple noun modifier, then members gallery can also be acceptable, just as member gallery would be.
My impression is that a construction like members gallery would be more acceptable in the UK, with its recent campaign against the greengrocer's apostrophe. In the US, it would be more likely to be flagged as an error by prescriptivist grammar pedants; linguistic descriptivists (such as most of the higher-rep users here) probably wouldn't have a problem with it, although some might consider it more awkward than the alternative.
