Well, in my application, you can select an image and put it in the form using opendialog. The problem is that the image won't be loaded, unless it's bitmap. So what do you suggest me to do?

Delphi 7 only supports bmp and jpg out of the box. To get wider image support you need to use a third party library. I recommend Mike Lischke's GraphicEx: http://www.delphi-gems.com/index.php/libs/graphicex-library

Based on the comments from the Andreas Rejbrand answers, I believe you should install the TGIFImage component. It supports Delphi7 and newer versions of Delphi.
Include the unit GifImage.pas to your project path from gifimaged2010b.zip, and add to your uses list. This will automatically add GIF in filters for openpicturedialog.

Multiple icons stored in one image file [closed]

Is it possible to store multiple small images or icons as parts of a single image, so that my webpage can get all the icons it needs from a single GET request. This would help my page load faster.
This is an example of the sort of composite image I'm referring to:

It seems to me that it is some kind of array of images put into one file. I'm hoping there is some way that i can use each individual icon in the image in a project.
These are called sprite sheets, there's a great article about them on css-tricks that should help you understand how they work on the web.

I have a binary-only copy of an application written in Delphi 7; as part of its execution, it writes some data into a text file (not in plain text).
Is it possible to extract the data from the file if I know part of the input data and have a copy of this file? (What if it's encrypted?) I have no idea about the structure of the mentioned file.
And no, I don't have source code for the application -- I think that's obvious.
Yes it's possible, you would have to reverse engineer this application first (IDA, HIEW) and/or debug it while it stores the data to the file, contact me if you need more help.

What I am doing as a part of my project is comparing and analysing all the noise removal and reduction filters there are in matlab.
Not able to find a comprehensive list of filters that have been built for this very purpose.
Well adding to my question, I wanted a list that would help me understand all the basics of noise removal using filters in matlab.
I have found various links such as this, which proved helpful.

When you have the toolboxes installed, you can also just look at the table of contents in the "Help" browser. Gives a pretty good summary of the options.

how can i create custom interfaces in xcode 4? i've seen programs like Kaleidoscope (http://designshack.co.uk/images/designs/kaleidoscope-for-mac.jpg) using custom controls or something not available for drag and drop on xode.
any help? thanks
You'll get better help if you take the time to craft more specific questions.
Since you're speaking generally, I'll answer generally: Xcode 4 will not help you create custom interfaces (at least not beyond letting you edit the code to build them). This is done entirely in code.
Learn to draw with Cocoa then learn how controls and cells work, then ask specific questions when you don't understand.

It looks like you're not sure what you're asking. Perhaps go and research the general idea of steganography.
Short answer: don't.
Slightly longer answer: it's a very inefficient form of steganography, it won't work for JPEG images, and for GIF/PNG it'll basically make your image uncompressable.
If you need stega for anything else but curiosity or school assignments, research existing offerings.
The technique you're thinking of is called Steganography. Here's a good post which explains the technique. http://www.dreamincode.net/forums/topic/27950-steganography/
