just looked at your links and i see my help may have been too general. that's a pretty specific scenario, and w/o downloading the whole theme i don't know exactly how it works. some quick thoughts tho:
- id say "An icon and UI design shop from Pixelmatrix Design." is the whole text of the post. i say this because it's wrapped in a .entry-content div
- the other stuff below it is pulled from 'custom tags' -- see classname of containing div.
- you could easily change the css to move all that under the img, but i think you'd have to tinker w/ templates to move the "An icon and UI design shop from Pixelmatrix Design." and not the other stuff.....
- i have no idea where the aforementioned image caption is. you'd prolly have to turn it on ... but if you did, it would probably end up underneath the image.
