We searched the region around the new INTEGRAL transient source IGR J18245-2452 (ATel #4925 #4927 #4929 #4934 #4959 #4960 #4961 #4964 #4981 #5003) using HST WFC3 and ACS/WFC imaging to characterize possible optical counterparts. The ATCA position of the transient source is R.A. 18h24m32.51s Dec. -24° 52' 07.9" (with a 90% confidence error of 0.5"; ATel #4981). Comparing the ATCA 8.5 GHz flux to the Swift/XRT measured 2-10 keV flux at the time (0.5-1E-10 erg/cm^2/s), we find that the radio/X-ray flux ratio is similar to that seen in e.g.
