Well basically I can't find anything regarding storing an image within a folder on the server, as appose to the SQL database. I have already written code to store the image within my database, but I also need to store the image as a physical entity for CSS purposes, here's a part of my code which can probably be used.

Does anybody know of an easy way to store Umbraco settings (Document Types, Media Types etc) on the file system in order to manage that data within source control?
Note: changes to settings made on the file system need to be easily integrated back into the CMS database.
Also, does anybody know of a way to package up settings from a development environment for rolling out to staging and live environments?

What is the best approach to storing images in a file system. Currently I am separating the images by day, month and then year. I am also hashing file name so that no two files will be stored with the same name. Lastly, how would I go about using the image file address in a forum?
View 3 RepliesWhich is the better alternative when allowing file uploads on a page (through a Gridview populated by a coded DataSet)? Store the image itself in the database or to store only the path name to the saved file in file system. If it matters, I do not expect to have more than a few dozen images stored in the database at any given time.

View 2 RepliesI have a requirement to allow users in a content management system to create their own image maps through a gui interface, which I have accomplished. But instead of saving the image map to the page code, I want to save the image map code to a database (sql), which I've also accomplished. When I started down this road in my head I was thinking the whole time that I'd just add the "usemap" attribute at runtime shown below where promo1.ImageMap holds the entire map code:
if(promo1.HasImageMap) imgPromotion1.Attributes.Add("usemap", promo1.ImageMap);
I guess I didn't think it though well enough, because it seems that "usemap" only expects the name of the existing map to use from the page code, and not the map code as a string.
how to apply the map from the database to the image at run time?

I can upload the file using my MVC application without any errors, however in the database the file stores in CoverFileContent as "0x0000000000000000......". All the other information relating to the file, e.g. MimeType, FileName, CoverID, etc uploads correctly. I took a wild guess that this wasn't correct so I downloaded the file (created a .net MVC file downloader). It seemed to download as the correct type of file, however I when I tried to open it, it told me I could not open it. I'll post some snippets of my code so people can see what I'm doing.

I have inserted breakpoints to debug the code, however coming from more of a business background I'm not sure what I'm supposed to be looking for. It seems that the array is being populated with 00000000s so I'm thinking this is a problem regarding the intake of the file.
