Image Management System for my Portal

[rinku257]

Hello,

I am getting a portal developed in which users can upload images and share it with their friends.

Although the portal is almost developed but I am stuck in some problem,when we are trying to upload images on the site,the image thumbnails are turning out to be really blurry and bad quality,and also the images itself are becoming blurry - the original images were of really good quality.

What could be possible reasons for this ?

And how do I get over this....

Is there any software available which can allow the users to upload the images and will automatically create a gallery of thumbnails.I am ready to pay the price for a sw like this.

Any kind of help would be great.

Thanks
