I have looked for hours for a solution on the forums but I couldnt find anything, hope anyone can help out here

I am running cmsmadesimple v1.0.2 and I had the cataloger module version 0.5.3 installed during the construction of our site.
Here is our URL : http://www.ie-solutions.com.au
Here is the site page in question : http://www.ie-solutions.com.au/index.php?page=portfolio
Everything was working fine until recently where we had to add a couple of new images to our portfolio. When I add a new page using the cataloger and I upload a JPG image, for some weird reason it wont show the image on the site. No changes have been made to the cms and I followed the same process I used when I added images before. Now all i get is "No Image Uploaded" on the page.
I have checked the permissions via ftp and everything seems fine, has anyone experienced this before?
Any suggestions or solutions would be very much appreciated.
Thank you kindly,
Glenn
