Imagine this: You have found the perfect theme for your blog. You’re looking at the theme demo and you’re simply in love with the design. The theme maker sounds great and you just have to have this WordPress theme. You buy and install it on your blog. You’re giddy about giving your blog a complete makeover and then this.
Your post thumbnails are all screwed up!
The images don’t look great and they’re all squished together. All the work you have put into your blog graphics has gone to waste. What now? Are you going to go back to your old theme and just forget about your new beautiful premium theme? No, and you shouldn’t. There is usually a very simple fix for this and your images will be as beautiful as before.
You have two options to remedy your stretched images. If you only have a few images on your blog, you can go ahead and reupload them. Once you have done this, the images will accept the dimensions set forth in your new theme. However, the more images you have already uploaded to your site and used in posts, the longer this work will take. It is not only reuploading the images but also reassigning the images to the specific blog posts.
Luckily, there’s a plugin for that!
This is your second option. Go to the Regenerate Thumbnails plugin site and install the plugin. Once the installation is complete, activate the plugin and navigate to Tools > Regen. Thumbnails in your dashboard. You’ll get an introduction to what the plugin does and then you can, with a single click, regenerate all of your thumbnails. The plugin does all the heavy lifting for you and you can relax and enjoy the way your new theme looks with your thumbnails.
