First impressions are that this website is kind of basic in terms of looks. No proper pictures, just colours and text. I can see the entire box, but that may have something with the fact that I have a resolution above the norm of 1024 x 768. The box itself rides a little low on the page - there is spare space above that could be utilized.
I do like the simplicity, but you really should have more than just blue, but not a kaleidoscope of colours.
The blue/white gradient inside the box where it says 'upload' is a little pointless, and also a little 'tacky', not going right to the edges and leaving an ugly white strip.
The way I would do it is just have the little box logo thing and the website name as the main header, then have the rest of the big blue text inside the box as dot points, a size larger than the rest of the text.
You seem to contradict yourself on the page in regards to size limits:
Maximum File Size: 1 MB (1024KB)
And then this a little further down ...
2 MB Maximum Upload File Size
It also lists "I agree to the terms of service" ... what exactly are the terms of service? They are nowhere to be seen ... this text should be a link to them, opening in a new tab or window.
You seem to have put the description of what your website does
right at the bottom of the page where the footer usually is. This should be the absolute first thing in your little box!
You also should expand the title of the page, which shows up in the bar at the top. Include "Unlimited Uploads - No Registration Needed". Also, a favicon wouldn't go astray.
This website here might help you with that.
Getting into the coding ... I know that you may not know HTML or CSS, but it's really easy to learn and way better than using WYSIWYG Web Builder. These programs often generate useless extra coding and in weird ways. I find
Notepad2 indispensable.
Again, the quality of these WYSIWYG editors is reflected in the
15 HTML errors and
2 CSS errors.
