How does changing a theme affect my featured images?

I am interested in changing the themes of two of my websites in the very near future. One thing that concerns me is that the featured image sizes would then need to change wouldn't they?

How would I go and then change the featured images for so many blog posts? This could take a huge amount of time.

I am sure there is a way to change my featured image sizes without physically uploading new images but what about when the featured image size is quite small, for example for my one there those images are 250*175. If I make those images larger they will look awful.

I am such a dummy when it comes to graphic design so please explain in a very simple way How does changing a theme affect my featured images?

If after changing your theme, your images don't look right. You can use the Force Regenerate Thumbnails plugin. I use this all the time on my WP sites that I have changed the theme on and it literally forces the regeneration of your images so they fit the theme better. That is a lot better option than having to reset and re-add your featured images in all your posts and should save you a lot of time not having to do that.

Of course, if that doesn't work as planned. You can always hire someone to do this for you as well. A reputable freelancer on here or create a WTB and find someone that way too. But that will involve trusting in that person and giving them your WP admin login details.

However, most new modern day themes today take into consideration your current featured images and should make them fit perfectly within that new theme so they don't look outsized or undersized. But the Force Regenerate Thumbnails plugin can usually fix that even if they aren't. I use it on a lot of my WP sites after changing the theme and it usually sorts them out for me without too much hassle. How does changing a theme affect my featured images?

Thanks MIke, that is really helpful. I was avoiding getting a new theme installed on my websites because I thought it would take way too much time and effort with the images. Now I am learning that there is a better way How does changing a theme affect my featured images?

LOL I should have known that there is always a better way to do things that manually. The way the world is going now with technology it won't be long until I can tell my phone to go make me some coffee.

While working with WordPress (as you probably do) it's always recommended to add large and quality images, probably not less then 800 pixels wide. That's for your future reference How does changing a theme affect my featured images?

It's true that different theme using different size of images to display in your post. But it doesn't mean that you will need to change anything. It just depend how your current theme is setup and how your future theme will work. Lately most of themes using 100% wide images so it can be responsive and mobile / website / tablet ready. You may test it by switching to new theme for few minutes and see how it look.

In case that you need to change sizes of featured images displaying in your posts, there is some plugins that will help you to resize all thumbnails in one click, will try to find which one works best, so i will let you know. But certainly you won't need to do it one by one manually! WordPress is very advanced CMS and people added many good features for it, there is fix for almost any problem you can have.

Thank you Anwebservices. Yes I was quite worried about that, I have a lot of posts and I am just not up for changing images manually! That is a reason why I was not wanting to look at a theme change quite yet.

It is nice to know that there are plugins I can use. I will check in with everyone and ask for help if I face any problems when I get there.

Back up everything and just do and test and see what happens. Changing from one theme to another is no easy task and you most certainly will have a lot of bugs if the 2 theme are not compatible.

My advice, never make change without a backup. If you mess anything up you can always come back to a state where everything was better. Do you have your website on a local server? If no, do the changes on local and only after multiple tests, upload everything in the live server.
