Unexpected Error when upload pictures

First of all I want to thank everyone at NopCommerce for your fantastic effort. As a start-up business I've found your platform a lifesaver in getting my business of the ground and I'm looking forward to contributing to your effort!

I have run into an unexpected error when uploading pictures to my hosted webserver when adding a new category. I haven't experienced this with my build on my own computer.

Following is the error I receive:
[quote]
Server Error in '/' Application.
Access to the path 'C:\Inetpub\vhosts\ishopshop.co.za\httpdocs\images\thumbs\0000082_100_80.jpeg' is denied.

Source Error:

Line 55:                 btnRemoveCategoryImage.Visible = categoryPicture != null;
Line 56:                 string pictureUrl = PictureManager.GetPictureUrl(categoryPicture, 100, 80);
Line 57:                 this.iCategoryPicture.ImageUrl = pictureUrl;
Line 58:

What I don't understand is why the system tries to access my personal computer instead of the webserver?

Hi Trevor,

Looks to me like this is referring to the file system on your web server, not your personal computer.

Need to have read/write permissions on the thumbs directory.

Hope this helps,
Ben

Hi Ben,

Thank you for your quick reply!

I was reading the error incorrectly, was wondering how on earth it could be pointing back to my system!

I think i've identified the problem. My website is hosted off site with an ISP and it seems they host it within an IIS directory which is subdivided to various virtual hosts, such as my domain.

I checked all my permissions and everything is in place but now i'm thinking that when the application uploads pictures it uses a temp directory which falls outside my permission. I think this is causing the problem.

Maybe I should somehow change the temp directory?

Here is the error message I just got: (I apologize for the lenght)

My website running on Vista Home also got the similar problem.

I have installed the NopCommerce at both of my PCs. The website set up at Windows XP sp2 works fine.
The one installed at Vista Home Premium is broken when it tries to open the Product page.
It errors out at the function:
...
NopSolutions.NopCommerce.Common.Media.PictureManager.GetPictureUrl(Picture picture, Int32 Width, Int32 Height, Boolean showDefaultPicture)
...

I think my problem is originally caused by privilege issues i'm having with my hosting server which then causes a database error since the program is trying to retrive a picture which is mostlikely only marked as being available but in reality was never uploaded. Giving you this error:

[quote]NopSolutions.NopCommerce.Common.Media.PictureManager.GetPictureUrl(Picture picture, Int32 Width, Int32 Height, Boolean showDefaultPicture)[/quote]

I've opted to build a custom uploading and management system to administrate my database. It's maybe not a fix for the problem but will help me work around it.

Trevor,

Just to confirm:

"i'm thinking that when the application uploads pictures it uses a temp directory"

NopCommerce uploads direct to the database when uploading images for category. It does not go to a temporary directory.

Hi,
I am facing the same issue. The issue does not happen when i access pages cached by the browser (that's what i think.. i maybe wrong). Its even happening for the default page (log below).

Can some one tell me what could be going wrong? My hosting is similar to Trevors description. Trevor, can you describe to me how you managed to work around this problem?

Thanks,
Srb.

Images are cached to disk at runtime. You need to make sure ASP.net has write permissions to the images directory.

Retroviz,
Thanks! That solved my problem.
