you need to contact your hosting company and ask them to give write permission

All permission is given to all folders but the issue remains same :(

Try to give write permissions to "Everyone" user (\images\thumb\ folder).

Full permission is being granted to each and every folder manually but the error remains same :(

Silver I know this doesn't mean much but this is DEFINETLY a permissions error I have see this error hundred of time before.  

Are you one doing the permission settings or the webhost?

The option to manage permissions is available in my hosting panel.
At first the site was running find about since i reuploaded the whole thing with a new design its giving this error.
I reconfigured each and everything again one by one.
It is surly a permission error but confusing is that full permission to read, write, execute scripts n exe all is been given to each folder n sub folder.

Really really confused, what i did wrong :(

What do you use to upload your website.. (I assume Filezilla)

I have also experienced this error, especially uploading larger DLL's filezilla sometimes misses up the transfer and these errors occur. Try old School FTP and just upload all your DLL's.

Hope this helps

I am using cute FTP and all files are uploaded successfully

THE PROBLEM IS STILL THERE :(

silver, when you set permissions, some hosts offer a selection of who to give permission to
in one hosting example you can choose to give one or more of the following permissions

read, write, execute, delete
and you can choose  to  give these permissions to

isusr_USERNAME
newtork service
everyone

as andrie  suggested, you should try giving permission to  everyone - if this is not an option in your control panel, then you should contact your hosting company to see if they can intervene directly for you
