Hello,
i think i find the error. If i upload a picture with 300 x 300 the media manager change the size to 116x 150. But in Backend the size for original images in media-manager is 300x300 and for tumbnails . Means if you put this image in a post it will blow up and than its looks very bad in quality. In Global i put the size for Tumbnails 150x150 and original 500x500. Means also here the Image will blowup and its looks very bad in quality.
So if you upload a image with 300x300 and the mediamanager resize the image, normally the image in mediamanger must be total clear and good quality. But in my media manager all pictures bad quality.
In the media manager you can set the size from a image manually over adapt. I make now a new tumbnail size and for the original image i force image dimensions to the original size before i upload this image. But this is not the right way, than the backend settings for images is virtually useless.
The Question is, why must be resize the image in the media-manager by automatic? Why is not possible thats i upload the image with original size in media manager and than i resize the image to default size in a Post? I think we have here two size conflicts. By the way its very confused.
So maybe somebody have i right idea how we can handle it.
