DB Image (Save/Retrieve/Watermark)






Wondering if anyone could help me here

I need to create a database in SQL2005 on a webserver (manually (not in code)), have registered users upload an image to a webserver not overwriting if the filename already exists but to append if required

Weekly, I wish to review the uploaded images in the uploaded folder, create a user & add the image(s) into the database programmatically for all users to be able to search

When the image(s) are in the database & are searched or shown (ex: profile shown with all those details/pics displayed but before displaying the pics on the form to watermark them. However, a profile could have 1 pick or it could have 20. I would like to have for example 4 pics being shown then the user to click next till the end of the recordset. Then do the same for another profile...

Uploading the file is fine but not to append if exists then maybe I should have an upload date as the filename (haven't decided)


Any help in VB.NET would be hugely appreciated


Thanks to all in advance

how to watermark image


hi everyone,

i am trying to watermark my image with logo....for that i am using this function...but i get no watermarked image...

can you tell me what is wrong with this piece of code...

     public Bitmap AddWatermark(Bitmap bImg, Bitmap logo)

Built-in Functions - Text and Image Functions in SQL Server

Text and image functions operate on TEXT, NTEXT and IMAGE data types. These data types are deprecated with SQL Server 2005 and should be replaced by VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) when possible. Alternatively you can also consider storing large string values using XML data type. Text and image functions are nondeterministic.

Future versions of SQL Server will not support TEXT, NTEXT and IMAGE data types. Columns with TEXT / NTEXT data type do not support commonly used string functions such as LEN, LEFT, RIGHT, etc. Furthermore, due to the large size of TEXT data you''re likely to see performance issues if you store such data in the database. However, at times you can''t help but use the TEXT / NTEXT / IMAGE data types (for example when supporting 3rd party databases when you cannot change the schema) - this is when text and image functions come in handy.

Program for Format Conversion of An Image

.NET provides extensive support for image conversion. Any image can be processed from one format to another. Most common formats to which .NET have support for are .BMP, .EMF, .GIF, .ICO, .JPG, .PNG, .TIF and .WMF.

Configuring Profile Image Export in SharePoint 2010

It's no secret that I am thrilled with the new social features of SharePoint 2010. I am most excited about the new Profile Picture handling. I strongly believe that the more we can show the faces of our colleagues to one another the more connected we will feel. Clearly Microsoft feels that way as witnessed by the many features that make use of the Profile Image like the Activity Feed and Colleagues list
