Blog posting problems

My web platform Weebly is doing some really annoying things! On the post below all the images are full width on the edit version, but then it publishes with some of them really small. That's particularly useless for this post where it's about texture overlays, that are invisible at that size! I've tried 'fixing' it and reposting, but whenever I refresh the public page of the blog it has the same problem. I don't know if it doesn't like me having so many bits of text between the pictures.

It's very frustrating! it's taken me about 90 mins for this post (and I had all the textures already in the pages). The textures must be really large files - it was freezing my (brand new) iMac for up to ten minutes just to import a page from Manga Studio!

​I'll have one more try just now, and then I'll leave it and try and fix tomorrow.

UPDATE
I've put horizontal dividers between the pictures and blocks of text, and that seems to have fixed it.
