Forgive me if I cannot explain this clearly - I'll do my best, though:
I'm using Blogger. I present my pictures, usually four to a post, in a 2x2 table. The pictures I post/upload are pictures I have exported from iPhoto, setting 850 as the widest size (iPhoto asks, this is what I happened to chose way back when I started). In the posts, they are shown small and represent a link, so when clicked, they show up, a single picture on one page, bigger - probably? the 850 - whatever unit.
When I read about MarsEdit, what attracted me was what seemed a simpler way of handling pictures, select from iPhoto directly, rest automatic.
However, it appears that the size / presentation gets to be involved....
-must be a 240x320 'thumbnail'? and the s1600 the 'real size?? or what??
Anyway, I quess I could figure out what sizes I want, so lets stay with the real issue: Is there a way for me to associate the (four) pictures with each their cell-in-the-table, to pe presented there at a certain size, and be clickable to the real size?
Sorry for another disappointing response, but no, MarsEdit doesn't currently have this level of fine-tuning for graphics: it is able to select and size only one image at a time, to be inserted wherever you want in the post. It doesn't have the ability to create multiple sizes (e.g. a thumbnail and full size) at once, and to insert them in a coordinated fashion like this.
