Hello
In
Real Estate you may set Crop Images or Resize
Real Estate : Settings -> Administrator Settings ->Common Settings->Crop image
If you set "crop images" - when we create thumbnail images - we crop from image central part, so size of all images same.
If you set "resize images" - when we create thumbnail images - we resize the image with save sides ratio, so size of all images will not same. But - images will look same as you upload.
Also please check:
Real Estate : Settings -> Administrator Settings ->Common Settings->House upload photo size
If image which you upload more then this setting - we will resize it to these size. This need for not give to your clients upload very big Real Estate images
