I'm looking for any suggestions for dealing with an odd problem I'm having with existing posts when trying to switch to a new theme. I've run into the same problem with multiple themes, and can't seem to figure out what's going on. The issue happens where there is a photo embedded in the post, and I have text wrapped around the photo (by giving the photo align="left" or align="right" attributes). If there is not enough text to fully wrap around the photo, the next post on the page appears to "overlap" the previous post (the previous post being the one containing the photo).
Any suggestions would be much appreciated. I'd really like to update the look of my site, but this issue is a major hurdle.
