Hello Shamil, I am not familiar with the subject but was looking at chart controls for use in aspx pages the other day and skimmed this article, http://aspnet.4guysfromrolla.com/articles/072507-1.aspx, that discussed a similar technique for putting chart images on web pages without actually creating an image file on the server. It may be of some use.

Subject: Re: [dba-VB] ASP.NET 2.0 - Displaying image from memory on WebImageControl Hi All, Here is the solution on my test site - http://shamils-4.hosting.parking.ru/Pics : as it's written in the article referred below to show a picture on ASP.NET Image control one has to create special helper .aspx page and pass to this page a parameter defining the source of the image - the latter could come from anywhere (file, database, external source (e.g. web service) etc.) or even be generated using System.Drawing... ...generated image is converted into array of bytes and then it's returned as binary stream within helper .aspx page... ...that sounds tricky but it works and I didn't find any less complicated solution - if anybody knows/will find another solution, which uses somehow an instance of HttpRequest/HttpResponse manually (in custom code) created and filled with an image bytes' stream - that would be useful here... Thank you. -- Shamil -----Original Message----- From: dba-vb-bounces at databaseadvisors.com [mailto:dba-vb-bounces at databaseadvisors.com] On Behalf Of Shamil Salakhetdinov Sent: Sunday, June 01, 2008 12:23 PM To: 'Access-D - VB' Subject: [dba-VB] ASP.NET 2.0 - Displaying image from memory on Web ImageControl Hi All, In ASP.NET 2.0 VB.NET or C# I wanted to load and image from a file (or get it downloaded/streamed it from somewhere but into memory) and then display it on an Image control *without write it to file*. I have found this sample (http://programming.top54u.com/post/Asp-Net-Display-Image-from-Database.aspx ), which gets image from db and displays them on Image control in a grid: I think I can adapt it to my case but if somebody can point m eon ready to use sample fitting my certain case I'd be very pleased to get it and to reuse...
