Sveiki visi atsitiko bėda, parsisiunčiau wordpress vieną dizainą, jis gan gerai atrodo , bet kai noriu pridėt naujieną turi rodyti paveikslelį o paspaudus rodytų teksta man nesigauna, man gaunasi tik juodas, o kai paspaudžiu rodo tekstą.
:
kur raudona ten turėtų but parayštas tekstas (nu viskas užtušuota) o kur juoda paveikslelis. bet jis neužtušuotas, jo nerodo.
čia kai paspaudžiu ant to juodo, tada rodo ir paveiksleli ir teksta. nors turėtų rodyt tik tekstą, o paveikslelį turėtų rodyt ten kur rodžiau..
o čia viska kaip padarau kur raudonai apibraukta ten keliu nuotrauka nu viska normaliai lygtais gal dizainas kaltas nežinau padėkit. ://

Nukopijuok paveikslėlio URL tada spausk
HTML (kur nuotraukoje pavaizduota)
tada pasirenki juostoje img išmeta lentelę kur įterpi nuorodą ir viskas. :)
