How (and when) is an image cached for an ASPX with ContentType = image/jpeg ?
I have a page 'GetImage.aspx' which takes 3 query string parameters: ID, Height, and Width. It uses the ID to retrieve binary image data from the database then scales the image to the given height and width.
The content type for the page is set to "image/jpeg" so I can use this page as the url for an <img> tag or ImageButton control. Examples:
<asp:ImageButton id="img" runat="server" ImageUrl="GetImage.aspx?ID=12345&Height=120&Width=200" /><img src=http://www.somedomain.com/GetImage.aspx?ID=12345&Height=120&...Delphi XE4 IOS: Download image and assign to image not working
In my App i download a image from URL and then assign it to a image at runtime.
It works fine on Windows but on the IOS app the image display is jibberish...
The downloaded image formats are jpg and png's.
// Download image from url
function DownloadImage(const URL : String): TBitMap;
var HTTP : TIdHttp;
Stream : TStream;
BitMapSurf : TBitmapSurface;
HTTP := TIdHttp.Create(nil);
Stream := TMemoryStream.Create;
Stream.Position := 0;
BitMapSurf := TBitmapSurface.Create;

I'm having trouble with Delphi XE4 and TreeView with stylebook.
I add a rss feed to a treeview with texts and pictures.
That works ok, but i want to add a link to high resolution images on the pictures shown in treeview.
Image OnClick only works on the first item in the treeview. In other words the rest of the items images is not clickable...
Any ideas ?

// PubDate : TText;
// Picture1 : TImage;
TRSSItem = record
Text : String;
LowResLink : String;

Hello,Is is possible to make a custom control where it's output is an image? When I try to do this the image works fine, but then all the html controls disappear from the page. I assume it's because the custom control's contenttype is set to image, and that overrides the rest of the page. I am trying to make something like a captcha control, where I pass it some text to make an image out of. I'm guessing I need to make a custom control that consists of an image tag that calls an .aspx page who's output is an image. But then how do I pass it ...JPEG image over Tranparent Image problem

I wrote a simple application with TTable component connected to a table with

Any Idea why, as I remember in ASA 5.xxx it worked well.

Summary: Insert image feature DOES NOT WORK with resized images
As my summary states, the insert image feature (of Thunderbird) does not
work if you resize your image (using the custom size function found in
the Image Properties Window).
It appears to work, and Thunderbird acts as if the email is sent, BUT IT
IS NOT. I repeat, no email is sent!

Hi I was wondering if anyone could help.I currently have a website that displays images, first as a grid of thumbnails and then when the user clicks on the image it shows them the full sized image. Currently these images are read from a server then resized and finally uploaded to the server. Currently I have the image resizer making two copies one thumbnail and one full size (although still resized from 1200x1200 to 600x600)I was wondering though if I was to use one image (the 600x600) and resize that to 120x120 using the <img style="width:120px; height:120px;" /> would cache...
