IWeb team: What's up with the repeated Blog publish errors?

Question

I maintain a simple, albeit many-entry -- all with photos, Blog on my daughter's .Mac iWeb site. Since the last iWeb update, I've started to encounter repeated difficulties when attempting to publish new Blog entries. All other updates on the site (Photo Albums, About Me, etc.) successfully publish, whereas new Blog entries pose the same problem, as follows:
"Publish error - Can't create the file "shapeimage_(blah, blah, blah).png. The disk may be damaged, full, or you may not have sufficient access privileges."
Many of you are VERY familiar with that ubiquitous message. However, my many attempts at troubleshooting and workarounds (e.g. publish to a folder, close open applications, delete files from iDisk, republish all, trash and rebuild pages, Domain reloads, etc. -- thank you, James Tseng, Varkgirl, et al.) fail to isolate the CAUSE of the problem. Specifically, what is the iWeb app doing while it assembles the Blog page(s) that results in the iWeb-centric "can't create..." error message?
Please note that I am doing nothing different when adding a new Blog. The process is the exact same one that I've employed for over a year, one that lets iPhoto/iWeb do most of the work (in terms of layout).
As most of you know, it's a time-consuming process waiting for updates to publish to the site, let alone wondering IF the updates will successfully publish.
Unless I am mistaken and more often than not, the "shape_image" error message is pointing to a file generated by iWeb as it readies the behind-the-scenes HTML for upload, yes?
I'd appreciate some specific troubleshooting and answers, please.
