In an extbase extension i want display images in the original imagesize. To have atomatic "width" and "height" i use in the template
<f:image src="{/path/xy.png}" alt="{imagetext}" />
But it doesnt work like i expected. Typo3 make a resize over this images so they are stretched. I have no idea why and cant find something about in the i-net. Do someone know how i can force Typo to use the original image-size? I could use a normal IMG tag, but then i have no width and height in the markup. And yes, it would not hard to write an own ViewHelper for this, but i cant believe that it could be nessecary.
I apologize for the bad english and thank you for the answer.
