The maximum image size that can be put as an avatar in your VKontakte account is 200 * 500 pixels. Loading an image of a larger size is pointless - it will still be proportionally inscribed in these frames.
It is necessary
Adobe Photoshop
Instructions
Step 1
Open Adobe Photoshop and create a new document. Immediately set the desired width to 200px and height to 500px. Set the resolution higher, but the bitness of the color mode is not so important, you can leave it at the default 8 bits
Step 2
Start with the background. You can simply fill it with color using the Fill tool in the panel on the left, or by applying a Gradient. In this case, a picture was used as the main background. To prevent it from distorting when typing in, hold down Ctrl and drag the corner, increasing or decreasing the image to the desired size
Step 3
Insert a photo that best reflects who you are or who you want to appear in front of your page visitors. After all, it is by the avatar that they will judge you in the first place. If you don't want to put a photo, then you can write your nickname in the background. In this case, it is worth playing with the text - use additional fonts, change the transparency and fill level, and the properties of the layer itself. In this case, the shadow and inner glow effects were used, and the layer overlay was darkened
Step 4
Add artistic effects with brushes. You can use the standard ones or find the kits on specialized sites. Before using the brush, create a new layer by pressing Shift + Ctrl + N.
Step 5
Create another layer to add a frame. Then select the Rectangular Selection tool and use it to select not the whole picture, but depart from the edges by a couple of millimeters. Press Shift + Ctrl + I, the selection is inverted. Fill it with white and set the Blending Method to Soft Light
Step 6
If you want to get a high-quality image, work in a professional graphics editor. If you do not know how to use it, then open a photo or picture in Paint and crop it approximately so that the image fits into the required frames. The inconvenience of the built-in editor is that you will not be able to precisely set the required dimensions.
