When working on the Internet, it is often necessary to upload your images to the site, for example, an avatar on a forum or photos to albums of social networks. Image upload errors may occur due to disabled Java-script in the browser
If you are unable to upload photos to vkontakte, please check if Java-Script is enabled in your browser. To do this, go to the "Tools" menu, the "Settings" item. Go to the "Content" tab, check the box next to "Use Java-Script" if it is not there. Click on the "OK" button. Problems loading photos can occur if you use plugins in your browser to cache images. Configure the plugin, refresh your browser and try to upload the photo again. Photos may not load due to the firewall enabled - go to settings, select Network Connections and the Advanced tab, click Disable. Check the size of the photo you are uploading, since many social networks have a limit on the size of uploaded images, for example, you cannot upload an image over 5 megabytes to the site vkontakte.ru with a different extension than GIF, BMP,.png"
