Ah yes, mon ami, that’s much clearer.
Here’s a method that might work for you... I just tested it (it had been a long time, and I think it’s what I did before).
Instead of having 2 calls on that page, you could try this. Make 2 documents under your gallery page (child documents). Mark them to not be in the menu (if desired). Then put a Maxigallery call into each page, and upload photos to each of them.
Now here’s the key. In the page where you want 2 galleries to appear, make this type of call:
[!MaxiGallery? &gal_query_ids=`50` !]
Paragraph of regular text here....
[!MaxiGallery? &gal_query_ids=`51` !]
And those numbers will correspond to the document numbers of your "subpages" of galleries. It worked great for me.
